Even celebrities have off days: Mila Kunis enlists family friend to jump start her Lexus after she let battery run flat

It's easy to imagine that the gilded existence of a Hollywood siren is hiccup free.

So it's edifying to see the luminous Mila Kunis, 29, looking seriously chuffed off as she waits for her car to be jump started on an LA street.

Needing a jump start: Mila Kunis has to enlist a family friend to help her get her car started this morning after the battery ran down

The beautiful Ted star had been a bit of
a plonker apparently by leaving her lights on overnight, something
most of us have done at some stage, and her battery ran down.

So a gallant family friend stepped in to jump start her Lexus, presumably as her own knight in shining armour, boyfriend Ashton Kutcher, 34, wasn't around.

He's a Lexus driver too, and also has a black version of the Japanese Mercedes.

Irritation: Mila probably could have dome without the morning setback

Mila has been dating her former That 70s Show co-star Ashton Kutcher since April and apparently things are getting serious.

An insider told Perez Hilton this week: '[Ashton] is totally into Mila. He's calling her his 'little wife,' which is cute but kind of odd since he's not divorced yet.'

But according to reports, estranged wife Demi Moore is taking longer than expected to finalize the divorce, which was announced last November.

Schoolgirl error: Mila waits patiently for her car to get fired up again

Although Kutcher, 34, and Kunis are said to be living together and were snapped holding hands as they boarded a plane in Bali earlier this month, they have continued to stay mum on the official status of their relationship.

In an interview with British Elle in August, the Ukranian born star went so far as to say she was 'totally single' and that she and Ashton were just friends.

'Listen, [Ashton and I] hang out. We've known each other for 15 years. We have mutual friends,' she said.
